SPOCK: Admiral, may I ask you a question?
KIRK: Spock, don't call me Admiral. ...You used to call me Jim. Don't you remember? Jim. ...What's your question? SPOCK: Your use of language has altered since our arrival. It is currently laced with, ...shall I say, ...more colourful metaphors. 'Double dumb ass on you' ...and so forth.
KIRK: You mean profanity. That's simply the way they talk here. Nobody pays any attention to you if you don't swear every other word. You'll find it in all the literature of the period. SPOCK: For example?
KIRK: Oh, the collective works of Jacqueline Susann. The novels of Harold Robbins.
SPOCK: Ah! ...'The giants'.
